This report describes the first record of the piscicolid leech Pontobdella macrothela from Mozambique waters and the first record of P. macrothela parasitizing a Grey Reef Shark (Carcharhinus amblyrhynchos). The leech, P. macrothela, was found attached externally between the third and fourth gill slits of a shark captured off Vamizi Island, Quirimbas Archipelago, northern Mozambique.

Distribution Record

In Madagascan waters, both Tetraclita rufotincta Pilsbry 1916 and T. africana Ren 1989 have been reported. Tetraclita rufotincta is more widely distributed than T. africana, extending to the western Indian Ocean and east Africa. Tetraclita africana is reported from Madagascar and no further distribution record has been made apart from its type locality. Both species have pink parietes and are similar in size, which could lead to identification confusion. In this study, we revealed that T. africana differed from T. rufotincta in having multicuspidate setae on cirrus III, a feature that can be observed with both light microscopy and SEM. Additionally, the tergum of T. africana has a rounded spur and a larger basi-scutal angle than that of T. rufotincta. However, since the name Tetraclita africana has been pre-occupied under the name Tesseropora (Tetraclita) wireni africana Nilsson-Cantell, 1932, we, therefore, propose herein a replacement name, Tetraclita reni nom. nov. Based on museum specimens examined, Tetraclita reni nom. nov. is present in northeastern and southern Madagascar and Mauritius but absent from Yemen, Kenya, South Africa, Aldabra and northwestern Madagascar, suggesting the distribution of T. reni nom. nov. could be confined to the south and northeast of Madagascar and adjacent waters.

Upeneus stenopsis n. sp. is described based on four specimens collected off northern Australia and Quezon Island,Philippines, at depths between 165 to 275 m and compared with four closely related species: the deep-water dwellingUpeneus davidaromi (Red Sea) and U. mascareinsis (Western Indian Ocean) and the shallow Indo-West Pacific species,U. subvittatus and U. vittatus. The new species can be distinguished from all other Upeneus species by a narrow caudalpeduncle and a combination of morphometric and meristic characters. This is the first record of a deep-water goatfish ofthe genus Upeneus from the Pacific. A juvenile Upeneus collected off Quezon at 127–142 m depth was also assigned tothe new species and compared to four similar-sized (69–79 mm SL) specimens of U. mascareinsis. A diagnosis is providedfor U. subvittatus, along with evidence of its occurrence in the Eastern Indian Ocean and interspecific comparisons. Thecontinued need to screen scientific fish collections for the occurrence of undescribed species that have successfully colonized and adapted to the depth zone surrounding the ocean margin is outlined.

AbstractA new endoparasitic monogenean of Paradiplectanotrema Gerasev, Gayevskaya & Kovaleva, 1987, Paradiplectanotrema klimpeli sp. nov., is described from the southern Balinese coast, Indonesia. The new species is much larger, wider and characterized by the longest dorsal anchors compared with the congeners. Ventral anchors and ventral bars are the smallest in the genus, with a distinct ratio of 1:1. This is the first species with a gladiator breast-plate-shaped dorsal bar, with a length:width ratio of 1:1. Oesophagi of the Common Grinner Saurida tumbil (Bloch, 1795) (Synodontidae) were infected (prevalence = 17%) at an intensity of 12 (1–21). This is the first record of the genus from the eastern Indian Ocean, and lizardfishes represent a new host family. We provide light microscopy (in situ in oesophagal folds), three-dimensional confocal illustrations and a morphometric comparison of all congeners, with remarks on the recently described first Indonesian endoparasitic Monogenea Pseudempleurosoma haywardi Theisen, Palm, Al-Jufaili & Kleinertz, 2017. First 28S DNA sequences for Paradiplectanotrema allocate the new species close to endoparasitc freshwater monogeneans. Its ecology differs from Pseudempleurosoma Yamaguti, 1965 by utilizing deep-water fishes instead of coastal, coral reef-associated hosts; however, both are infecting schooling, bottom-dwelling fishes.

Vriesea is the third largest genus in Bromeliaceae and is broadly distributed along of the Brazilian Atlantic Forest. We report the first record of Vriesea correia-araujoi for the Espírito Santo state, in Cachoeiro de Itapemirim municipality, southeastern Brazil. So, the geographic distribution of this species is extended to beyond the Serra do Mar complex, since it was registered as endemic to the coastal region of Rio de Janeiro state. A map with the distribution of the species is presented, as well as the list of examined material.

Morphological Differences

An immature female specimen of rough shark was collected south of Reunion Island in the Madagascar Basin in 2009 aboard R/V Dr. Fridtjof Nansen, representing the first official record of the family Oxynotidae in the western Indian Ocean.  The specimen is herein identified as Oxynotus sp. due to morphological differences with its closely similar congeners O. centrina and O. bruniensis regarding morphometrics, shape of dorsal, pectoral and caudal fins, shape of the head and colouration, refuting the hypothesis of occurrence of these two species in the region.  These results indicate that Oxynotus sp. is possibly an undescribed species.  A general description of the external morphology, external morphometrics and photographs of Oxynotus sp. are provided.  The specimen has a hepatosomatic index of 36.33% which reveals that it was possibly approaching maturation, suggesting that a viable population of Oxynotus sp. exists in the western Indian Ocean.  Intraspecific variations in O. centrina from the Mediterranean Sea and eastern Atlantic Ocean are also noticed, requiring further taxonomic scrutiny.

A New Species

Abstract Doflein (1904) accidentally transposed the figures for the third maxillipeds of two species of pinnotherid crabs he described, a mistake which has taxonomic consequences. The species he described, Pinnotheres villosissimus Doflein, 1904, from Sumatra, is here referred to its own genus, Trichobezoares n. gen. The specimen Doflein identified as “Pinnotheres sp.” from South Africa was referred to a new species, Pinnotheres dofleini by Lenz (in Lenz & Strunck, 1914) partly based on Doflein’s (1904) incorrect figure of the third maxilliped. To stabilize the taxonomy of this species, Doflein’s specimen is selected as the lectotype; fixing the species as a member of Afropinnotheres Manning, 1993. Pinnotheres pilumnoides Nobili, 1906 (Djibouti) was differentiated from the taxon T. villosissimus partially on differences in the third maxilliped. It is redescribed, figured and shown to be a second species of Trichobezoares. The correct authorship for the species established in Lenz & Strunck (1914) is also discussed.
